Can I rotate objects the with 3 orbits around it like in Unity or SketchUp?
If you press R the object will rotate on the view axis. If you press R then X, the object will rotate on the X axis only. If you press R twice it will rotate on both axis except the view one. If you press R and then Shift + X it will rotate in both axis except X.

If you set the curve in the selector on the header of the 3D view you will have your "Rotators" around the object.
